In this message, Shri K. Sreekant applauds the frontline control room personnel, who are the backbone of GRID-INDIA.
He discusses on the 22.2 GW
of wind and solar being scheduled by GRID-INDIA. Due to this, new challenges have emerged, such as Inverter Based Resources (IBRs), and Accuracy of Forecasts. New entities like Battery Energy Storage Systems (BESS) and Green Hydrogen Electrolyzers would soon be part of the electricity grid. To keep pace with these developments, Technical Standards for Grid Connectivity and a robust Compliance Monitoring System is to be put in place. Cyber Security has also emerged as an important area.
Notable achievements in 2022 include Automatic Generation Control (AGC), pilot extension of Security Constrained Economic Despatch (SCED) with ~65 GW capacity under its operation, launch of National Open Access Registry (NOAR), and Green Energy Open Access portal. GRID-INDIA employees wrote and published 23 technical papers. Actions in respect of upgradation of our Ener
